I have a 5 kg 6' Caution Trespass for the surf, great on the surf and smooth on the chops. If it is 14 mph wind and up that is what I use, if it less then 14 mph then I use my 6' Firewire Potatonator surfboard (3.5 kg), which I also use for surfing when there is no wind. I have tried it in winds more than 14 mph and it starts to bounce to much not as smooth as the Trespass.

So you actually kitesurf in waves, in wind less than 14mph ? (which is 6 m/s and less or below 12 knots)

Amazing - I've never seen anyone do that (not even being out), especially not in warmer conditions

What kitesize do you use, and what do you weigh ?

Or is it another unit you had in mind maybe ?

I would say, that it takes A LOT more wind for me, before any "light" waveboard would get bouncy in chop (78kg)

we have some days with less than that and I've used the fly kite...I guess it is 15 meter or maybe a bit bigger side off shore..it is different than regular kiting. Works in small waves, and with light kites.

6 lb 9 oz with stomp pad and fins. easily could have made it lighter but It's bombproof scratch proof and dent proof anywhere that matters. (top and rails)For the most part I throw it around and don't even use a board bag.

Cool!. You sir are a BOARD BEATER!How do you ride (strapped/strapless monster waves) You doin lot's of strapped airs? land flat much? Got any pics of your boards that were bifricated?deckpads? What boards broke?Love to see how and where they are failing....description if you don't have pics.

I suspect any custom builder could make you something a bit more bomber,However making it light enough that it's not a turd may take some talent. Knowing your history though I would not put you on a 6lb board....but If you're breaking em all the same, and I can see why I could certainly take out the weak link without a lot of weight. Designing for impact and bending require different strategies to make the best use of the weight. Yet many builders don't understand the relationship and differences between bending strength, impact strength and stiffness as well as how to get the best improvement from each for the least weight.

I'm sure it will open up some good discussion from the other knowledgeable builders on the forum as well.

How do you ride (strapped/strapless monster waves) - strapless, small windswellYou doin lot's of strapped airs? - yes land flat much? - more than I would likeGot any pics of your boards that were bifricated? - limited picsdeckpads? - heel traction pads onlyWhat boards broke?Love to see how and where they are failing....description if you don't have pics.

Slingshot Celeritas Strapless 5'8" 5lbs 12.6oz w/ 3 SS fins (epoxy?)- Board snapped in front of front foot from rail to rail after 90 mins of light use. SS said tough luck and offered me nothing.Only the top deck broke, including the bamboo, the bottom of the board is intact.

Dumpster Diver 5'7" 6lbs 8.8oz w/ 3 F4 fins (fiberglass) -Buckled and delaminated under front foot. I bought this board used. It was a mistake all around. The CI construction has no chance of standing up to kiting.

SharpEye Blowfish 5'5" 6lbs 2.4oz no fins (fiberglass) - Buckled and delaminated under front foot. This board was well used when purchased and served me well before failing.

Rusty Pirhana 5'8" 6lbs 11oz w/ 3 F4 fins (Surftech)- Deck of the board broke through under heal of front foot. Repaired with carbon, snapped it on one rail in same location today. I bought this board used and ride it hard.

Rick Burhans Westwind 5'11" 6lbs 11.8oz w/ 3 M3 fins (fiberglass)- Snapped under or slightly in front of front foot. I bought this board used and rode it hard.

I want to try Lib Tech but am waiting for them to go on sale. New materials/construction techniques make these boards pretty tough (according to the hype). And earth friendly as you will not be throwing your broke boards into the local landfill.

Most kite surfboards are WAY more reinforced for impact but are often times heavier than sin.

As for the SS celeritas Ive seen a lot of broken celeritas boards they rarely survive a roll in the wind or a crashing onto shore and upon inspection appear poorly reinforced, relying on a thin skin of bamboo and glass. (although I haven't seen under the front foot. there may be structural foam there)

It appears the primary failure mode for you is Heel denting causing delamination, followed by compression buckling of the unrestrained skin resulting in the failure.

I'd definitely recommend a tuffite or "sandwhich" construction. as it creates an outer beam that reduces the point load on the underlying low density foam.

In addition From my testing a front stomp pad has significant effect on the height from which the board can take a heel first landing without denting and I would recommend this unless you absolutely hate using one...your board sizes look too small to paddle anyway.

Your riding doesn't seem crazy so a lightweight off the shelf tufflite or "sandwich" construction with a front stomp pad would likely save you killing more boards without getting into anything custom.

If you're breaking these then I would want to see some more pics of failures to decide if you needed thicker structural foam (damaged underlying eps, causing failure) , higher density structural foam, (HD foam dented causing delamination), or more glass underneath your front foot. (foam sheared) to prevent further failures. But now we're getting heavier.

Although beautiful and good at reducing point loads when combined with sandwhich construction, for weight concerns I am not a big fan of wood venirs, from my testing I can engineer significantly more bang(literaly)/gram out of s-glass and HD foam than wood but do so at a higher price. That stated I have not tested all wood types exhaustively as initial results indicated this to be a waste of time. .
